To all whom, it may concern:

Be it known that I, FRANK A. MAGOWAN, a

citizen of the United States, residing in Trenton, in the county ofMercer and State of New Jersey, have invented certain new and usefulImprovements in Flush-Tanks, of which the following is a specification.

This invention relates to a specific form of flush-tanks which are madeof ceramic or vitreous material and in which the tank is inclosed in acase so that a little space is left be tween them on nearly all sides,whereby the case is not in direct contact with the water in the tank,and hence the water cannot cool the case sufficiently to causecondensation or sweating upon the exterior of the latter.

The specific form of the invention herein claimed comprises a closedbottom case molded in one piece'with the contained tank and having acommon rear wall, but separate bottoms, ends, and front walls, andjoined at their rim portions, studs being formed between the tank andcase and integral with both to make a strong structure and the case alsobeing -ioined to the tank at their rims and provision being made wherebythe case i takes the overflow, if any, from the tank.

The case in this form of the invention is provided with means whereby itmay drain into the same flush-pipe that receives the water from thetank, said pipe opening into the case aswell as into the tank.V

In the accompanying drawings, Figure 1 is a sectional frontelevationshowing the tank, case, and studs, all integral, with theirappurtenances.l Fig. 2 is aV front elevation of the apparatus. Fig. 3 isa sectional side elevation thereof. Fig. 4 is a plan thereof on asmaller scale.

The tank may comprise rear and front walls 1 and 2, side wall 3 and 4,and bottom 5, forming a box and molded of clay or 'vitrified ware,preferably without glaze or finish. It is supplied'with water through apipe 6,`hav ing the usual nozzle 7 and iioat 8 for regulating theflow.Thetank discharges through a flush-pipe 9, having at its top any usualor suitable apparatus for controlling the discharge-such, for instance,as a valve 10, whichmay be operated in any way, as by a link 11, a lever12, and chain 13. The top of the pipe is shown inclosed in apacking-ring 14, which may be of rubber and is inclosed in a cup 15,formed below .the level of the tankfloor, and having top and bottomflanges 16 and 17, which confine the'packing 14, it bethe tank ingintended that said cup may contain the packing-ring when the tank issold to dealers. The diameter of the hole in the bottom flange 17 may begreater than that of the pipe, so as to give clearance for the latter.The case, which is also formed of either ceramic or vitreous ware,comprises vsides 18 19, a front wall 20, and a floor or water-tightclosed bottom 21, and, as will be seen, forms a vessel surrounding thetank on its sides and bottom and is larger than the tank, so that an airblanket or space 22 is left between the tank and the case on all sidesexcept the back. -The rear wall 1 of the tank is extended at 23 to meetthe sides of the case, thejlatter not having a separate rear wall. Therear wall is also shown as extended to form a vertical flange 25 on thesides and bottom of the case, throughwhich may pass bolts 26 forsupporting the apparatus upon a wall.

In manufacture the tank is molded separatelyfrom the case, and they maybe united, as by means of studs 32, which form supports between the tankand case not only during firing, but also during the subsequent life ofthe structure, serving to give a great degree of solidity to the same.The supply-pipe 6 passes through a stud, being packed by a ring 6E.lThese studs, it Awill be understood, are molded to or become integralwith both the tank and the case, so that all form one piece of warewithout break or joint.

In order to drain off the overflow and, as well, any` condensation fromthe outside of proper, I cause the Hoor 21 of the case to sop`e toward acup or pocket 34, formed below the cup 15 and having a bottom opening35, through which passes the flush-pipe 9. The latter is provided withweep holes or perforations 36 within the cup 34 and, as will be seen,comlnunicates with the case wholly independentl of its'communicationwith the tank. ithin the cup 34 is provided a packing-ring 37, which isinclosed between flanges 38 and 39 in the manner a1- ready explainedwith referenceto the packing-ring 14, the perforations in said fiange's'38 and 39 being of preferably larger diameter than the pipe 9 to affordsuitable clearance for the latter. The case is shown closed at its topand there united with the tank to give the appearance of a single-walltank and to strengthen not only the rim, but the entire structure. Thisjoint or union between the case and tank is indicated at 45, and belowit are provided suitable holes 46 to carry off loe A the other.

an accidental overflow from the tank. It Wil be understood that the tankand vcase may be joined in this manner, even if one is made of adifferent grade of clay or ware from The case may be made of highgradeclay suitable for lazing, while the tank may be made of a mo dedsubstance not suitable for glazing, and still they may be united attheir edges into an integral struc'- ture, or, if desired, both case andtank may be made of a lowade vitried ware, such as commonly pro uced inpotteries, and a suitable glaze ut upon the case without glazing thetank),` the inside of the case and outside of the tank of courseremaining unglazed. Hence the device, although having a highly-finishedap e'arance and excellent desi n, may be manu actured at trivial cost.

A though the joint or rim 45 forms a continuation of the brim of thetank, still it will be understood that there is no liability of sweatingor condensation upon the case, be-

cause, owing to the distance of the uplper part of the case from theupper part oft e tank, the case may remain at the temperature of theroom, whilethe tank is cooled a little by the water-that is to say, thecase is too far away from the tank for the water to cool the former eventhou h continuous with the tank. Moreover, t ere is a circulation of airin the 'space between the tank and the case. The overflow-openings 46may be made very i frequent and extensive, so that there will be a'minimum of convection of heat between the top of thetank and the top ofthe case.

Certain variations may be resorted to within the scope of this specificform of the invention and portions of the improvements herein claimedmay be used Without others.

Having thus described Amy invention, I claim- .1. A closed-bottom casein combination with a flush-tank, both .of vitreous or ceramic ware, thetank within the case and slightly 'separated therefrom, and studs moldedin one of said elements and extending to the other thereof. 2. A caseand a flush-tank both of vitreous or ceramic ware, the tankl within thecase but sli htly separated therefrom, and studs molde to both of saidcase and tank elements. Y

3. A case and a flush-tank both of vitreous or ceramic ware, the tankwithinthe case but slightly separated therefrom, and studs of ceramic orvitreous ware between the tank and case and molded together therewith,so that the case, tank, and studs form an integral or single piece.

4. A Hush-tank and case slightly separated therefrom and molded togethertherewith, and studs extending from said tank to said case and integralwith both thereof.

' 5. In combination, a flush-tank and a case in which it is containedand from which it is slightly separated so as to prevent the case fromsweating, the tank and case molded toether of ceramic or vitreous Ware,and a ush-pipe opening into said tank; said case having a drainterminating at said pipe, and the latter having an opening into whichthe case may drain. g

6. A Hush-tank in combination with a case in which it is contained andfrom which it is slightly separated, and a Hush-pipe opening into saidtank; said case having a pocket or cup at said pipe, and the latterprovided with in which it is contained and from which it is Y4slightly'separated, and a Hush-pipe opening into said tank; said casehaving a pocket or cup at said pipe, and the latter provided with anopening through which water collecting in said cup vmay discharge; and apacking or yielding material between said pipe and said casing.`

8. A flush-tank and case molded in one piece of vitreous or ceramicware, and slightly separated, and joined at their rim portions; andstuds between said case and tank and integral therewith.

9. A closed-bottom case, in combination with an inclosed tank, bothlmolded in one pieceof vitreous or ceramic ware and having a common rearwall but separate bottoms,
